TRANSFER STOCK-CAR.

SPECIFICATION forming part of Letters Patent N 0. 733,300, dated August 4, 1903. I

Application filed January 20, 1902. Serial No. 90,4=74. (N model.)

covered new and useful Improvements in Transfer StockOai-s, of which the following isa specification.

In the accompanying drawings, which make part of thisspecification, Figure I is an end view of a car and a set of bins equipped with my invention. Fig. II is a side view of a car provided with my invention.

My invention relates to bins and cars for transferring ore, coke, coal, limestone, or other material therefrom to furnaces or other places of deposit.

Heretofore it has been necessary to provide the severalbins along a track with separate gate-lifting devices. Ordinarily the gates of the bins are opened by'levers attached to the front of the bins and it is necessary to have one of such levers for each gate. With a .large number of bins, necessitating a great number of gates, the cost is quite an item. At some furnaces eachgate is operated by y myapparatus all such mechanismisdispensed with and the levers for operating the gates are attached directly to a frame on the car.

1 designates as a whole a car of ordinary construction, provided with the usual weighing mechanism and hopper-shaped box. Be cured to the ends of the car are standards 2 2,

held vertical by braces 3 3 and tied together by a cross-bar 4, extending longitudinally of the car and at a convenient distance above it for the purposes hereinafter specified.

Braces 5 5 prevent movement of the standards lengthwise of the car. Levers 6 6 are 3 pivoted on opposite sidesof the cross-bar 4: by means of the pin 7. "Each lever has at of suflicient weight one end a pendent cord or hand-pull 8, provided with astirrup 9 at its lower end. At the end of each lever, opposite the cord 8, is a horizontal pin or dog 10, which extends outwardly away from the cross-bar.

sufficiently above the car-track to allow the cars to pass thereunder are two opposite rows of bins 11 11, the end bin only of each row being shown. Each bin has a gate 12 to be closed by gravity.

'Fastened on the front of each bin is a Z-shaped lug 13, having its free bent edge extending downwardly. The ends of the levers carrying the pins are heavier than the other ends, so that they normally occupy the position of the lever at the front of Fig. II. 14 is a post standing between the levers 5 5 and provided with a cross-arm 15, reaching laterally over each lever as a stop therefor.

When a transfer-car is run on the track, the frame composed of the standards 2 2 and the cross-bar 4 extends up between the rows of bins or along by the side of a line of bins, if there is but'a single row of them.

The operation is as follows: An empty car is run under the bins and stopped with a pin or dog 10 under a bar 13 on a gate 12. The operator then pulls down on the stirrup 9, causing the lever to rock and the dog 10 to lift the gate. Upon letting go of the stirrup the gate falls by its own weight and cuts oif the flow of ore. If there is a row of bins on each side of the car, the gate on each side can FFICE..- 7

be operated Without moving the car, as the bars 13 on the gates are directly opposite. While I have shown one form which my invention may assume, I do not desire to be limited to the precise details thereof, as many modifications as to form, proportions, or arrangement may be readily made by those skilled in the art to which it relates.

' Having described my invention, I desire to secure by Letters Patent of the United Statesl. A substantially horizontally traveling conveyer, a stationary receptacle having a gate which when opened delivers the contents of the receptacle into the conveyer, and means carried by the conveyer and having movement relatively thereto, said means being adapted by such movement to positively opensaid gate.

2. A traveling conveyer, a projection thereon, a stationary receptacle having a gate, which when opened delivers the contents of the receptacle into the conveyer, and means carried by the conveyor and having movement relatively thereto, said means being adapted by such movement to positively open said gate.

3. A stationary receptacle having a gate, a traveling conveyer, and a pivoted device on conveyer and having movement independent thereof, the said movement being capable of 15 positively operating said gates.

7. In a device for operating opposite gates, a traveler, a standard thereon, levers on the standard, means on each lever for engagement with a gate. 220
